DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cuff block for a finger arterial sphygmomanometer using a non-invasive sphygmomanometer, and more particularly, to a cuff fixing device for fixing a cuff using a cuff for partial compression. By locally fixing the joint at or near the joint, it is possible to reduce a blood flow disturbance and a hindrance to the bending operation of the finger during the measurement of the blood pressure of the finger artery.

[0002]

2. Description of the Related Art Conventionally, a non-invasive finger arterial sphygmomanometer currently has three measurement principles of a cuff vibration method, a volume vibration method and a volume compensation method. Among them, the cuff vibration method causes the cuff to generate blood vessel pulsation, that is, blood vessel wall motion as pressure vibration,
This is a method of indirectly measuring the blood pressure from the vibration change pattern of the pressure vibration. In addition, the volume oscillation method uses a photoplethysmogram sensor to measure the volume pulse wave just below the cuff compression part (vascular wall motion).
Is directly detected to measure the blood pressure. Further, the volume compensation method is a method in the volume oscillation method in which the cuff pressure is balanced with the blood pressure by performing volume compensation so that the intravascular volume becomes a non-load volume. According to the volume compensation method, the measurement of cuff pressure together with the systolic / diastolic blood pressure per beat,
There is an advantage that the blood pressure curve can also be accurately measured.

In the non-invasive finger arterial sphygmomanometer according to any of the above-mentioned methods, as a method of measuring the blood pressure of the finger artery, a band-shaped cuff having a predetermined width is wound around the finger to be measured, and this cuff is measured. A method of measuring the intravascular pressure, that is, the blood pressure of the finger artery, using the fact that the pressure applied to the artery propagates to the arterial blood vessel immediately below the cuff, has been used.

[0004]

In the above-described method for measuring the blood pressure of the finger artery, the cuff pressure at the time of measuring the blood pressure is generally set within the range of the arterial blood pressure or higher than the systolic blood pressure. For this reason, the cuff pressure always maintains a high pressure for the venous blood pressure which is much lower than the arterial blood pressure.

[0005] By the way, a finger blood vessel has two arteries located on both sides of the finger along the bone, while a vein runs near the subcutaneous area of the finger while a plurality of blood vessels intersect in a complicated manner. Therefore, the vein of the finger to be measured at the time of blood pressure measurement is constantly compressed at the cuff-attached site, and blood circulation disorders such as congestion occur on the peripheral side together with the cuff-attached site.

[0006] In addition, by applying pressure when the band-shaped cuff is wound around the outer periphery of the finger, various muscle tendons controlling the bending motion of the finger are pressed and the expansion of the tissue immediately below the cuff is prevented. Has a problem in that the operation is greatly obstructed and the bending operation becomes difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and it is possible to reduce a blood flow disorder of a finger to be measured and a hindrance of a finger bending operation during measurement of blood pressure in a finger artery. The purpose is to obtain a cuff block for an arterial sphygmomanometer.

[0008]

To achieve the above-mentioned object, a cuff block for a finger arterial blood pressure monitor according to the present invention is provided.
A cuff for measuring blood pressure from the pulse is attached to the cuff fixture
The cuff fixing is applied to the skin of the finger to be measured at several points.
It is intended to be supported.

With this configuration, it is possible to avoid a state in which all the veins are compressed only by compressing a part of the veins of the finger to be measured. It does not cause blood circulation disorders. Also,
Since it does not hinder muscle tendon compression and tissue expansion, the finger can flex freely.

FIG. 4 is a perspective view of a cuff block for a finger arterial blood pressure monitor.

This embodiment shows an example in which the finger arterial blood pressure cuff block is attached to the index finger 1 of the left hand. Here, the structure of the index finger 1 will be described. The fingertip of the first joint 1a is the distal joint 2, the middle joint 3 is between the first joint 1a and the second joint 1b, and the finger joint of the second joint 1b and the third joint 1c. The interval is the base section 4. In addition, finger arteries 6 and 6 are located along the left and right of each phalange 5 of the index finger 1, and finger veins 7 that intersect in a complicated manner as shown in FIG. I have.

The cuff block according to the present invention, which is generally designated by the reference numeral 10, for the index finger 1 as described above
It is mounted on the base section 4 between the first joint b and the third joint 1c.

As shown in FIG. 4, the cuff block 10 for a finger arterial sphygmomanometer is, in this example, a cuff fixing tool 11 entirely formed of a ring-shaped plastic molded product or metal molded product.
A cuff 12 is held by the cuff fixture 11.

The cuff fixing device 11 has a special shape, and is provided with a linear bifurcated support portion 11 from the cuff holding portion 11a.
b and 11b, and the cuff holding portion 11 is formed into a single band-like portion 11c on the side substantially opposite to the cuff holding portion 11a.
a.

On the other hand, the cuff 12 is formed of a substantially disk-shaped molded product having a hollow body made of, for example, a flexible rubber material or vinyl material, and the cuff 12 is supplied with air or a liquid. A measuring device (not shown) is connected via the terminal 13.

The cuff 12 is mounted on the skin so as to correspond to the position of one finger artery 6 (in this example, the side facing the thumb) at the center of the base section 4.
2 is held by the cuff holder 11a of the cuff fixture 11. At this time, the cuff fixture 11 is inserted from the tip side of the index finger,
By making the cuff holding portion 11 a overlap the cuff 12, the cuff 12 can be stably held at the central portion of the base section 4.

At this time, the fixing point of the cuff fixing device 11 attached to the index finger is such that the bifurcated support portions 11b, 11b are connected to the second joint 1b (base phalanx) and the third joint 1c (base phalanx). And the cuff 12 is fixed to the index finger only at three points where the cuff 12 is fixed to the base section 4 via the cuff holding part 11a. The band part 11c is loosened to the skin except at these three fixed points. The other parts do not come into contact with each other.

The fixed portions of the bifurcated support portions 11b, 11b may be fixed to the skin portions near the respective joints other than being fixed to the second joint 1b and the third joint 1c.

Thus, by supplying air or liquid to the cuff 12 to generate a cuff pressure, the pressure of the cuff 12 is transmitted to the finger artery via the skin and subcutaneous tissue, and the blood pressure can be measured.

According to the present invention, since the cuff block for a finger arterial blood pressure monitor is used as described above, the cuff fixing device 11 does not uniformly press all the finger veins running in an intersecting manner. . Therefore, the blood flow in the finger arteries and finger veins is not affected at all during blood pressure measurement, and a sufficient circulation of arterial blood and venous blood to the measurement site and its periphery can be sufficiently ensured, and blood pressure measurement for a long time can be ensured. Thus, blood circulation disorders such as congestion can be avoided beforehand, and it is suitable for use in a cuff block for a finger arterial sphygmomanometer such as a volume compensation method.

Further, since the expansion of the tissue due to the compression or movement of the muscle tendon of the finger to be measured is not hindered, the finger can freely bend.

Furthermore, since the expansion of the tissue due to the finger movement is not hindered, the influence of the force on the cuff 12 and the blood vessel immediately below the cuff due to the finger movement is small, and accurate blood pressure measurement is possible even when the finger is bent. Becomes

In this example, cuff fastener is denoted by reference numeral 14, are made from the molded article of the pulp plastic moldings or metal overall shape having a resilient feature of the substantially C-shaped. One end of the cuff fixing device 14 has a cuff holding portion 15 for holding the cuff 12 so as to cover the entire cuff 12, and the other end facing the cuff holding portion 15 is supported by the finger to be measured. It becomes the unit 16.

The cuff fixing device 14 configured as described above holds the cuff 12 placed on the skin at the cuff holding portion 15 so as to correspond to the finger artery, and the cuff holding portion 15 and the supporting portion 1 together.
At 6, the finger can be mounted by pinching the finger to be measured. That is, since the cuff fixing device 14 in this case can be fixed to the finger to be measured only at two points, only a part of the veins is compressed, and the cuff fixing device 14 is similar to the cuff fixing device 11 described above. Since all veins are not compressed, sufficient circulation of arterial blood and venous blood to the measurement site and its periphery can be sufficiently ensured, and blood circulation disorders such as congestion can be avoided even in long-term blood pressure measurement. can do.

The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.

In this example, the cuff fixing device 11 and the cuff fixing device 1
4 and the cuff 12 are configured separately, but the cuff holding portion 11a and the cuff holding portion 15
2 may be integrally formed. By doing so, the cuff block can be easily attached only by attaching the cuff fixing device to the finger to be measured and positioning the cuff 12 at the measurement site.

Further, the measurement site of the finger to be measured is not limited to being attached to the base section 4, but may be attached to the middle section 3 above the base section or to the base section or middle section of the middle finger other than the index finger. The same measurement result as in the above case can be obtained even if it is attached to

Further, as the fixing points of the cuff fixing device to the finger to be measured, other than the two-point support and the three-point support, there are multiple points within a range that does not affect the congestion due to the compression of the vein of the finger to be measured and the bending operation of the finger. It may be supporting.

Further, the cuff block for a finger arterial blood pressure monitor according to the present invention has a structure in which the size of the cuff fixing device can be freely changed or different in size because the thickness of the finger differs between a man and a woman. It can be dealt with by preparing several.

Further, in the case of a ring-shaped cuff fixing device, a part of the cuff fixing device is cut apart from being inserted from the tip of the finger to be measured, and the cuff fixing device is opened and spread from the separated portion by utilizing elastic force. A method of attaching to a finger to be measured may be used.
